low bandwidth ogg playing.

Xmms doesn't play ogg files well if they are encoded at low bandwidths.
I've made a test file (short sample of a jimi hendrix tape) which sounds
OK when played through ogg123, but awful when played through xmms.

see www.niftybits.ukfsn.org/misc/test-ogg-direct.ogg

This has a bitrate of about 12 kbps mono, which is useful for peer to peer
broadcasting where 2 upload streams are needed to keep the stream fanning
out.

It plays OK in zinf as well.

It was encoded using the following parameters:

 oggenc -b 12 -M 18 --managed --resample 11025 --downmix
